| Abstract: | The kinetic behaviour of butadiene polymerization with Ni(naph)_2 Al (i-Bu)_3-BF_3·OEt_2-ROH Catalyst system was studied. The reaction mechanism between BF_3·OEt_2 of C_3H_(17)OH, the effects of polymerization temperature, catalyst's concentration on the polymerization was investigated. The kinetics eqnatiou of poiymerizalion was thus established. It could be expre ssed as -d(Bd)/dt=kpC]Bd]=kpfNi]. Bd] The apparent activation energy was 20. 6kcal/ mol and tile other kinetic parameters was obtained. |
